libpayload: bin/lpgcc allow to call without files

When building libflashrom ontop of libpayload, meson calls the lpgcc
wrapper with -xc but without a file to obtain information about the C
compiler. To make this work guard $_LIBGCC with -xnone in the lpgcc
wrapper. -xnone tells the compiler to interpret the following files of
libpayload by their suffix, not the privious given -x option.
