Fix perl 5.22 'left brace in regex deprecated' warnings

With the recent stabilization of perl 5.22, app-misc/muttprint-0.73-r3 now returns the following warnings when printing from mutt:

Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\\newlabel{ <-- HERE LastPage}{{}{(\d+)}}/ at /usr/bin/muttprint line 1638.
Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\\newlabel{LastPage}{ <-- HERE {}{(\d+)}}/ at /usr/bin/muttprint line 1638.
Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\\newlabel{LastPage}{{ <-- HERE }{(\d+)}}/ at /usr/bin/muttprint line 1638.
Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\\newlabel{LastPage}{{}{ <-- HERE (\d+)}}/ at /usr/bin/muttprint line 1638.

These warnings will become errors in perl 5.26 apparently. The simple patch to resolve these warnings is attached.

Right now I don't have the hardware to test it. Please test and reopen if necessary.

app-misc/muttprint-0.73-r4 compiles, installs, and runs fine here without the warnings from -r3. Leave as RESOLVED->FIXED. Thanks!
